A refresh button on the watchlist, for when you know you've added something to a third-party wishlist, but it hasn't been pulled through yet.
Alternatively, just a countdown timer to when the next sync will happen.
Thanks for the suggestion! I’m doing the final testing to a new version of the watchlist which should provide an automatic refresh when new data arrives; and also hopefully fix the speed issues.
But I hadn’t thought of adding a button to schedule a sync of the external sites; nice one!
